Cushion pad

ABSTRACT

A cushion pad includes a cushion body made of flexible material such as sponge, foam, resilient fibers or resilient rubber and has a slot defined therethrough. An inclined surface is defined in a front portion of a top of the cushion body. The slot is located corresponding to the user&#39;s spine.

FIELD OF THE INVENTION

The present invention relates to a cushion pad for relief of pressure onthe spine, especially for reducing pressure to sacrum.

BACKGROUND OF THE INVENTION

A common problem for those who sit for a long period of time is lowerback pain which is caused by the pressure applied to the nerves aroundthe lumbar vertebrace or even the deformation of the disk of cartilage.In order to reduce the pressure applied to the part of the spine, mostof the people put a pad as shown FIG. 5 on the seat portion of chairs soas to provide a cushion feature. However, after a short period of timeof use, the cushion feature disappears because the cotton or foam in thepad becomes a solid block which has no flexibility at all. Thetraditional way to release the pressure applied to the spine obviouslyis not satisfied.

The present invention intends to provide a cushion pad that includes aslot which is located corresponding to the position where the sacrum ofthe user so that the spine bears less reaction force from the chair andspine is protected.

SUMMARY OF THE INVENTION

The present invention relates to a cushion pad made of flexible materialsuch as sponge, foam, resilient fibers or resilient rubber and includesa slot defined therethrough. An inclined surface is defined in a frontportion of a top of the cushion body. The slot is located correspondingto the user's spine.

The present invention will become more obvious from the followingdescription when taken in connection with the accompanying drawingswhich show, for purposes of illustration only, a preferred embodiment inaccordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 and 2, the cushion pad “A” of the present inventioncomprises a cushion body 1 made of flexible material such as sponge,foam, resilient fibers, or resilient rubber, and has a slot 11 definedtherethrough. An inclined surface 12 is defined in a front portion of atop of the cushion body 1. The inclined surface 12 extends to the frontedge of the cushion body 1. A cover 2 is coated on the cushion body 1and is made of air-permeable material.

As shown in FIGS. 3 and 4, the cushion pad “A” is put on the seatportion of a chair “B” and the user sits on the cushion pad “A” withthighs contacting the inclined surface 12 of the cushion pad “A” and thespine of the user is rested in the slot 11. The inclined surface 12provides the user a comfortable status when sitting on the cushion pad“A”. The sacrum of the user's spine does not contact the cushion pad northe seat portion of the chair “B” so that no reaction force is appliedto the spine. The slot 11 is a longitudinal slot and extends toward thefront edge of the cushion pad “A” so that the user is allowed to adjustthe position when sitting on the cushion pad “A” while the sacrum islocated corresponding to the slot 11.

While we have shown and described the embodiment in accordance with thepresent invention, it should be clear to those skilled in the art thatfurther embodiments may be made without departing from the scope of thepresent invention.
